I found a pretty nice website that has the broker bond for around $100. The site is Jane Bond Insurance Agency
I submitted a request for a quote, but I hope they don't sell my info to a bunch of companies trying to sell me bonds.
A $10K broker bond (in California) is $50/yr, with a 2 year requirement, totalling $100. No need to submit info for quotes.
These bonds are pretty easily obtained (i.e., not as much scrutiny as say a financial obligation bond).
I'll email you the app, as long as you are in California.
